“…This application is in line with the report of successful use of morphometrics of A. mellifera by Andere et al (2008) and the use of wing landmarks in bumble bees by Aytekin et al (2007). Finally, front wing measures discriminated area populations better than hind wing measures using a geometric morphometric method.…”

a b s t r a c t honeybee (Apis mellifera ) populations are usually distinguished using standard morphometric methods, mainly based on multivariate analysis of distances and angles. recently, geometric morphometrics, another method of statistical analysis of shape, has been developed. this research was conducted on european honeybees in iran in 2012. multivariate analysis on hind wings identified significant differences between honeybee populations from different areas and significant differences in centroid size of fore wings in different geographical areas (F = 10.6, p = 0.000). populations from nine areas were classified using discriminate function analysis based on shape variables of fore and hind wings. crossvalidation tests based on discriminant functions of front wings correctly classified 68.2% of the colonies, and cross-validation tests based on discriminant functions of hind wings correctly classified 43% of the colonies.

“…Twelve traditional morphometry parameters previously described for honey bees (Andere et al, 2008) were measured following the protocol developed by Padilla et al (2001). Variables considered from each body part were as follows: right hind leg (metatarsal width: LegL4 as shown in Figure 2A); proboscis length (ProbL; Figure 2B); right fore wing [five angles (G5, G6, G8, G9, G11, G13)]; cubital index measured according to Ruttner (1988) (Figure 2D); and right hind wing (three internal lengths: wing L4, L5, and L9) (Figure 2C).…”

European lineages of Apis mellifera were first introduced into America for beekeeping purposes. A subsequent introduction and accidental release of A. m. scutellata resulted in hybridization events that gave rise to Africanized populations that rapidly spread throughout the continent. In Argentina, Africanized honey bees (AHBs) have been mostly detected in northern regions of the territory, and represent a valuable genetic resource for the selection of stocks with advantageous characteristics for beekeeping. The objective of the present study was to profile honey bee colonies of wild origin with potential beneficial traits for apiculture using morphological, molecular and behavioral traits. Honey bee colonies chosen for evaluation were located in two different agro-ecological regions in north-western Argentina (Tucumán province): The Chaco Depressed Plain (Leales apiary) and the Piedmont (Famaillá apiary). Each apiary was surveyed three times during the 2017–2018 season (mid-season, wintertime, and early spring) for: brood population, phoretic Varroa level and defensive behavior (run, fly, sting, and hang). At the midpoint of the beekeeping season colonies were also characterized by morphometry (45 variables) and mitochondrial haplotypes (COI–COII intergenic region). Apiaries studied showed similar patterns throughout the beekeeping season, for most of the characteristics monitored. However, significant variation in defensive behavior parameters was found between apiaries at the different times of evaluation. Twelve of 45 morphometric variables also showed significant differences between apiaries. The mitochondrial haplotype analysis revealed a high representation of African A4 and A1 haplotypes (91%) in both apiaries. Haplotype variation was associated with morphometric and behavioral traits. Multivariate analyses [principal component analysis (PCA) and principal coordinate analysis (PCoA)] including morphometric and behavior variables explained 65.3% (PCA) and 48.1% (PCoA) of the variability observed between colonies in the first two components. Several morphometric parameters and “fly” behavior were mainly associated with the separation of the colonies. The results from this study point to a possible association between morphometric and behavioral variation and the adaptation of honey bee colonies to differential agro-ecological conditions. We discuss how the detected variation between apiaries can be used for the selection and preservation of honey bee ecotypes in regional breeding programs.

“…Several methods have been applied to take body measurements; (i) stereomicroscope with an ocular micrometer (Ruttner et al, 1978;Mattu and Verma, 1983;Edriss et al, 2002;Stanimirovic et al, 2008;Gencer and Firati, 2005;Mostajeran et al, 2006;Adl et al, 2007;Marghitas et al, 2008), (ii) Photomicroscope (Morris-Olson, 2002), (iii) Projecting mounted slides onto a TV screen (Kandemir et al, 2000), (iv) Using computer-based methods mainly for forewing and some body characteristics (Rinaldi et al, 1970;Ruttner, 1988;Meixner, 1992;Shanbhag et al, 2000;Meixner et al, 2007;Shaibi et al, 2009;Miladenovic et al, 2011;Abou-Shaara and Al-Ghamdi, 2012;, and (v) Special programs using image analysis systems and the IMAGO program (Padilla et al, 1992). Also, software programs like Image-Pro Plus version 3.0.1 for Windows 3.1 and Media Cybernetics were used (Andere et al, 2008). A simple method for measuring body and wing morphological characteristics was presented by Abou-Shaara et al 2011where they used photoshop program; this method was named the Scan Photo method while Miladenovic et al (2011) used AutoCAD program to take the measurements.…”

The morphological characters of honeybees were measured using a Scan Photo technique (SPT) that involves the use of a stereo binocular microscope and Photoshop program combined together. The body parts of a honeybee worker were scanned as images after they have been dissected. Photoshop program was used to view the images and their characters were measured using the ruler of the software program. While measuring the chosen morphometric characters, a significant difference was observed when the SPT and using a binocular microscope were compared. The measurements of 7 morphological characters of honeybee workers from nectar-feeding colonies were compared with those of Pepsi cola feeding colonies. There are more than 24 different subspecies of honeybees (Apis mellifera) classified based on their morphological characteristics. As a result, morphological characteristics are usually considered when classifying honeybees. Many authors for various reasons have used body morphological characteristics as well as sets of wings to classify subspecies of honeybees. Such characteristics have been defined overtime and sourced from diverse studies. Of all body morphological characteristics studied so far, wing venation characteristics have been given more attention. Up to now in Saudi Arabia, there are no specific review articles that focus mainly on Apis mellifera jemenitica body morphological characteristics. Consequently, information gathered from sampling and measurement methods, and factors affecting these characteristics especially mouthparts is to recognize the possibility of finding any changes in configuration as a result of feeding on soft drink. The morphology and functional anatomy of the mouthparts are examined by dissection, light microscopy, and supplemented by feeding type observations. This manuscript focuses on the differentiation of the proboscis which is formed by the glossa, in context with feeding from natural nectar and soft drink. In the literature, morphological innovations have been described for insects, particularly forbees.These innovations are critical for the production of differentiation in proboscis such as proboscis hair formation and modification. The present study showed that the proboscis of honeybees feeding on Pepsi is wider, thicker and very hairy compared to the natural feeding honeybee's proboscis. The morphological structures of the head, proboscis, hind leg, and wings were measured for the two groups of bees, the first naturally nourished with nectar, and the second feeding on the drink Pepsi Cola. The results showed significant differences in nectar and Pepsi feeding in different length measurements of head (
